# Service bulletin SM2201

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

SM2201 Ford 7.3L PATS Module Familiarization PATS Immobilizer Module: Purpose, Functionality, and Troubleshooting The PATS \(Passive Anti\-Theft System\) or SPM \(Security PATS Module\) is a new piece of required hardware that has not been used historically on Ford powered Blue Bird Vision Buses. The intent of this memo is to provide a basic overview of its function, purpose, and basic diagnostics. The 7.3L PCM hardware requires a PATS handshake to enable engine crank. The PATS module, sometimes called an SPM, is paralleled to Ford CAN only and not to J1939. It’s mounted above the MPX module \(non\-NEA\) within the PDU and on NEA models it is located on the ledge above the chassis PCB. The PATS module is purpose built for non\-Ford VIN applications using the 7.3L engine. It is paired to the PCM via an IDS bi\-directional function, to which one needs Ford PTS log in credentials for IDS access to the immobilizer database.
